A 6Cl.O-kg skier starts from rest at the top of a ski slope 65.0 m high.
(a) H frictional forces do 10.5 k1 of work on her as she descends bow fast is she going at 1he bottom of 1he slope?
(b) Now moving horizontally, 1he skier crosses 8 patch of soft snow, where μk = 0.20. H the patch is 82.0 m wide and the average force of air resistance on the skier is 160 N. bow fast is she going after crossing the patch?
(c) The skier hits a snowdrift and penetrates 2.5 m into it before coming to a stop. What is the average force exerted on her by the snowdrift as it stops her?
